Overheating for no reason I can tell

1995 Lexus ES300, The vehicle overheating or running much hotter after driving about 9 miles. I have replaced the waterpump, head gaskets, thermostat, cap, reseviour, jumped the fan into high speed to verify fan operation. checked and double checked the connection to the solenoid on the power steering pump. I am lost as to what else could be the problems?? It seems to still be using / losing coolant but, there are no indication of a leak. Had the coolant checked for crankcase vapors and 0 were detected. There is no odor of coolant in the exhaust and no smoke from the tail pipes as well. Any ideas at this point would be great!!

How would power steering fluid get into the engine, no that is not it. Have shop do a quick look and see what they say the smoke is, if it has a sweet smell then you have coolant getting into the engine.

When the car is not moving, "air" is not cooling the car down. So it is over heating. Your fan only comes on for so long and then stops. An overheating car can be a small problem that leads into a huge problem. Find the leak asap. Your thermostat could be bad, cooling sensor, radiator, hose(s) or water pump. Are you refilling it with antifreeze often?

When you refilled the radiator did you burp the system to get all the air out of the lines if you get trapped air in the coolent system then the coolent doesn't circulate like its supposed to and gets hot spots. If you arent confident on how to do it take it to a shop and they will get you squared away. (To do it yourself with the vehicle cold park with the radiator at the highest point take off the radiator cap and let the vehicle run till it warms up and then watch for air bubbles and then top off your radiator and put the radiator cap back on your done)

the power steering pump would have nothing to do with the engine overheating but the water pump certainly would, but before you go to the trouble of replacing the water pump you need to be certain that is the problem as there are other issues that can cause overheating, like the thermostat or a blocked radiator, the mechanic who said it was the power steering pump quiet obviously don't know too much about engines............hope this helps......cheers.

whilst driving air is flowing through the rad ,so no problem ,stationary for any length of time and yes it will overheat for a variety of reasons.Make sure it only has antifreeze and no water ,fit an aux electric fan manual controled from an old vehicle in the scrappy .

I was able to release the headlamp bulb on the 1995 Lexus es300 by removing the rubber cover and releasing a pin that keep the bulb in place. I willhave to purchase a HELO replacement bulb, part numberSKU: HEL.1637160.11701

Your car has front disc brakes, the disc's are running out of true, as u apply the brake this causes the steering wheel to shake, the higher the speed the more u feel this, the solution is to have the front brake disc's machined true again on a brake lathe or if they are to thin replace them.

Flush the fluid every 30-45k miles. I work for lexus and they make solid cars and transmissions but some es300 transmissions from that year range fail (a very small percent) they do only replace transmissions. After the replacement the cars are fine, its not necessarily anything the owner did.Ive seen mixed results from shops that rebuild these transmissions as they don't do them everyday, those shops see alot more gm ford and chrysler vehicles and many of their models fail before 100k.
